With the SB24 and SB34 sandwich valves, Rexroth provides a consistent modular system for auxiliary directional and hitch control valves available to mid- and high-end tractor manufacturers.

  • Features significantly more compact design for simpler installation and flexibility adapting it to individual tractor concepts
  • All sections can be freely combined with each other independently of the type of actuation (mechanical/electrohydraulic) or flow rate 
  • Provides compact control block with uniformly aligned ports to ensure optimal integration in machines
  • Design based on previous SB23/SB33 family 
  • Includes mechanically operated configuration as well as electrohydraulically actuated valves with a flow rate of up to 120 l/min for the SB24 and 170 l/min for the SB34 
  • Modularity in function and flow allows for a high level of configurability of the working hydraulics which is enabled by standardization of flange ports and widths (44 mm)
  • Combination of up to seven valve sections for different flow rates in control block reduces piping efforts and provides exactly the energy required by each of the consumers
  • Using end valve version eliminates need for end plates of the control block (which are necessary in other systems), resulting in a smaller installation space
  • Reduces energy consumption of the mobile hydraulics using load sensing and supplies the consumer consistently
  • SB24-M, SB24-EHS1 and SB34-EHS1 valves lower internal friction and pressure losses in comparison to previous versions, aiding further reduction of diesel consumption and increasing maximum usable hydraulic power
  • Supports broadened pilot oil pressure range of 17 to 25 bar, enabling easier use of external pilot oil supply to lower system costs
  • Exchangeable pilot modules make maintenance easier
  • Electronics are encapsulated and protected from external influences
